Figure 5.

Simulation results for side view of the electric field distribution $E_y$ (snapshot in time) for a molecule emitting in the center of the narrow channel of Figure 1 at the cut-off wavelength ${\lambda }_0=750nm$. The geometry is similar to Figure 3a, but (a) $l_{ch}=2\mu m$, (b) $l_{ch}=1\mu m$, (c) $l_{ch}=0.5\mu m$.
